Here is a link that you can use to see the problem.

I cross-posted this to comp.lang.java.programmer.
Note that I have directed Follow-Ups to c.l.j.help only,
please set follow-ups as you see appropriate.

For those who have just joined this thread, the OP
has an applet that is failing in IE7. I thought it was
the Eolas patent thing, but that should not apply to
scripted applets - as I understand these to be.

Any thoughts?

And to the OP.. SheeEEEsh.. the only reason I don't bother
saying 'and make sure we don't have to jump through hoops
to see the applet' is because I thought it was 'intuitively obvious'..
my bad.

And... (see below)

Use IE 6 to see what is an administrator applet. As previously
mentioned, IE 7 gives the problem.

I am able to view other java applets on other web sites using IE 7.

Also, here is some code. It's quite a bit, but I did take out what I
thought would definately not be required by you (variable declarations,
etc). Hopefully, you will see something obvious and not have to spend
too much time on it. I'm stumped. It all looks fine to me.

I have also include html code from the page that is supposed to fire up
the applet right after the applet code.
